This is an iron-based superalloy which features an austenitic structure with high amounts of nickel and chromium. A286 (or Incoloy) is ideal for high strength and corrosion resistance up to 704°C and for lower stress applications at high temperatures. Learn more about A-286 fasteners.

Benefits:

Low temperature capabilities including ductility, non-magnetic, high strength to -196°C

Good strength and oxidation resistance at temperatures up to 1300°F

Low stress application above 1300°F

High oxidation resistant in continuous service up to 1500°F (816°C) and intermittent service to 1800°F (982°C).

Excellent corrosion resistance to high temperature atmospheres such as those encountered in jet engine applications

Operating aircraft engines at higher temperatures improves energy efficiency and hence fuel efficiency. To do so, aerospace engineers rely on super alloys like Inconel 718 for the hot sections of turbo reactors. Inconel 718 is an age (precipitation) hardened alloy that retains its high yield strength and usability to 1800°F. Did you know that 50% of the Inconel 718 produced is used solely for the manufacturing of aircraft engines in their essential parts including blades, sheets and discs?

Both military and commercial aircraft utilize titanium for its superior strength-weight ratio, helping them to be lighter and more fuel efficient without sacrificing safety and longevity. In addition engine and airframe parts which need to withstand temperature swings from subzero to 600°F utilize titanium’s high temperature strength performance. Learn more about titanium.

Benefits

High strength to weight ratio - Titanium grade 5 is about 4x stronger than steel but 45 percent lighter

When temperatures are hot, this super alloy can take the heat and maintain its strength. Waspalloy is a nickel based alloy which delivers strength and reliability at extreme temperatures as high as 1600°F/870°C. Waspaloy derives its high-temperature strength from a solid solution of molybdenum, cobalt and chromium, and its age-hardening elements aluminum and titanium. When hot, Waspaloy a stable and adherent oxide layer protecting its surface. It is often used for hottest sections of jet engines and other gas turbines where other super alloys such as Inconel 718 might fail due to extreme heat. Learn more about Waspaloy fasteners.

Benefits:

Temperature limits of 1200°F (650°C) for critical rotating applications and up to 1600°F (870°C) for stationary parts

Relatively impervious to under conditions of frequent thermal cycling, as well as continuous exposure to temperatures up to 1900°F

Low thermal conductivity

Excellent creep rupture strength

Fastener Uses:

Parts where burning jet fuel can cause parts to become immensely hot for extended periods of time
